Common Functions

With the Re-EQ function, you can compensate a
soundtrack whose high-frequency content is too harsh,
making it more suitable for home theater viewing.
This function can be used with the following listening
modes: Dolby Digital, Dolby Digital EX, Dolby Pro
Logic II Movie, Dolby Pro Logic IIx Movie, DTS, DTS-
ES, DTS Neo:6 Cinema, DTS 96/24, THX Cinema,
THX Surround EX, THX Ultra2 Cinema, and Multi-
channel.
With the Late Night function, you can reduce the
dynamic range of Dolby Digital material so that you can
still hear quiet parts even when listening at low volume
levels—ideal for watching movies late at night when you
don’t want to disturb anyone.
Notes:
• The Late Night function can be used only when the
input source is Dolby Digital, Dolby Digital Plus, or
Dolby TrueHD.
• The effect of the Late Night function depends on the
material that you are playing and the intention of the
original sound designer, and with some material there
will be little or no effect when you select the different
options.
• The Late Night function is set to Off when the AV
receiver is set to Standby. For Dolby TrueHD sources,
it will be set to Auto.
Using the Re-EQ Function
Press the [Receiver] Remote
Mode button, followed by the [Re-
EQ] button.
Press the [Re-EQ] button again to turn
off the Re-EQ function.
